Calamities caused due to heavy rain recently

Now that we understand something about levees and floodplains, we can add to this list the possibility of levee failure. Other river systems have a reference level that is not sea level. Sediment Flows Sediment flows occur when sufficient force is applied to rocks and regolith that they begin to flow down slope.

The result is denuded hillsides which exacerbate the severity of landslides; since tree cover impedes the downhill flow of water. Discharge is not linearly related to stage because discharge depends on both the depth and width of the stream channel, or more precisely, on the cross-sectional shape of the channel.

Discharge is plotted on the Y-axis, and dates are plotted on the x-axis. Submarine debris flows — Moving material breaks apart. Soil types dependent on climate Different soil types have different capacities to absorb moisture.

Some common examples of natural disasters include floods, hurricanes, earthquakes, tsunamis, tornadoes and volcanic eruptions.

Uttarakhand — rainfall Houses are submerged as trucks flow in flood waters of the Bhagirathi River in Shrinagar district in northern Indian state of Uttarakhand, India, Monday, June 17, Volcanic Eruptions Volcanic eruptions are one of the deadliest forms of geological natural disaster. Here is a list of the different forms of natural geological disasters that can occur.

Avalanches occurrences are common in Kashmir, Himachal Pradesh, and Sikkim. You may copy this content, create derivative work from it, and re-publish it, provided you include an overt attribution to the author s.

Soil type is to a large extent dependent on climate. Tsunamis can also be caused by underwater volcanic eruptions. Louis, idealized cross sections of the River are shown here for points a, b, and c in the diagram above.

Other deadly occurrences of tsunamis were caused by the Messina earthquakeItaly and Krakatoa volcanic eruptionIndonesiawhich resulted in estimated deaths of 75, and 36, people respectively.

Sediment Flows - debris flows down hill mixed with water or air.

Volcanic ash released into the atmosphere when mixed with water might form a concrete-like substance that can damage roofs of buildings. Other deadly occurrences were the Kursha-2 Soviet Union firestorm in that killed about people and Cloquet fire U.

Such holes are most common in karst landscapes. Sweden and Norway had a large number of wildfires that broke out with heat waves this summer. The air quality is so bad that San Francisco, Stockton and Sacramento became the world's three "most polluted cities" on Friday, according to Berkeley Eartha nonprofit that aggregates data from air-quality monitoring sites, worse than hot spots in China and India.

The avalanche, caused by the Ancash earthquake, was about meters wide and 1. There are varying estimates that peg the number of natural disasters per year across the world in the range of Such curves are called isohyets, and the resulting maps are called isohyetal maps.

The river brings a large amount of silt, which, along with the large volumes of water, led to a breach of the embankments and caused severe flooding in northern Bihar and parts of Nepal. Downstream flooding If large amounts of rain fall over an extended period of time over a large region, downstream floods also called regional floods may occur.

The magma travels up the inside of the volcano, and pours out over the surrounding area as lava. The severity of a wildfire depends on flammable material present, weather conditions, vegetation density and topography of the area. The state government says the flooding killed 1, people and 5, animals.

The caliche zone acts as an impermeable layer though which water can only penetrate with difficulty. In this article, we look at various types of natural disasters and their deadliest occurrences from the past, that continue to remind us that Nature is indeed the most powerful force after all!

Hurricanes cause far greater damage to coastal regions and typically weaken over land.Heavy rains and earthquakes can also trigger slumps.

Falls - Rock falls occur when a piece of rock on a steep slope becomes dislodged and falls down the slope. Debris falls are similar, except they involve a mixture of soil, regolith, vegetation, and rocks. due to improper surveillance of natural calamities. Table II gives year wise frequency of accidents and the losses incurred to Konkan railway due to natural calamities [4].

Nagoya city suffered inundation problem many times due to water ifongchenphoto.com Isewan typhoon in September 26, and Tokai heavy rain occurred in September are the major water disaster causes severe flooding in th e Nagoya city. Heavy rain has caused more flooding in northern England, with homes evacuated in Lancashire and Yorkshire, and rivers overflowing in Manchester and Leeds.

Vulnerable people are being evacuated. PITTSTON, Pa. -- Part of Pittston Cemetery looked more like a lake in Thursday’s heavy rain. Tombstones were just peaking out over the flood waters and bubbles were coming up from the ground.

Incidences of very heavy rainfall in recent years In early Januaryheavy rain warnings were issued around the North Island. The southern Hawkes Bay area was the worst affected, with up to mm of rain falling on it over an hour period.
